Fourstroke 01 is a high-performance XCO bike that exceeds the demands of the world's best racers.
Featuring exclusive Autodrop technology and unparalleled APS dual-link suspension with 100mm of front and rear travel, the Fourstroke 01 is able to set itself apart from the competition with a premium carbon frame.
This revolutionary bike features integrated protectors and is designed around the progressive BWC geometry, and can now mount two water bottles in the front triangle for long distance rides.
Stay ahead of the competition with the Fourstroke 01 TWO paired with a SRAM Gx Eagle AXS drivetrain, a RockShox SID SL Select+ fork and RockShox SIDLuxe Select+ shock, a set of DT Swiss XR 1700 wheels with 25mm internal width, and a BMC Autodrop integrated seatpost dropper.
AUTODROP TECHNOLOGY
Your brand new secret weapon is the first fully integrated automatic seatpost dropper, which allows you to lower the seatpost very quickly and effortlessly, to push yourself further and faster, even on the most technical XC trails. With an intuitive two-position adjustment, our lightweight Autodrop technology gives every rider that split-second advantage that can be decisive in a race.
OPTIMIZED APS SUSPENSION
More traction equals more speed, and that is precisely our goal. Superior kinematics tuning and improved suspension performance provide full traction, great efficiency and active suspension on every terrain. This complete, new and improved suspension system is unrivalled on the race track.
GOFAR
This bike born to collect successes is versatile by design. Allowing you to go far, the Fourstroke 01 has been optimised to accommodate two water bottles and offers 62 mm clearance for modern 2.4" XC tyres.
REDEFINED GEOMETRY
The BWC Race was conceived for a fast, progressive style of riding, designed to attack the steepest trails with an improved head angle of 66.5˚ and a long front end. Short 429mm chainstays provide power and proven traction on the most technical sections. Lowered bottom bracket and 76.7˚ seat angle ensure perfect weight distribution and handling.
BOOST DESIGN
Full throttle! The redesigned frame excels in torsional and pedalling stiffness for unparalleled power delivery. A real quantum leap that takes one of the most successful XC race bikes to a new level.
EASY TO USE PROTECTION
The Fourstroke 01's internal cable routing is guided through the front frame, lower passages and rear frame, making maintenance a breeze. An integrated fork cap, chainstay protector and lower link guard protect the frame for durability, while an access on the seat tube provides easy access to Autodrop maintenance.
